To ctZZ whom, t Hetty 00h/cern.`

Beit known that I, ERNST GEORG BEEN- HARDKRTING, a subject of the Emperor of Germany, and a resident of Berlin, Germany, have invented a new and Improved Coke- Oonveyer, of which the following is a. full,

` clear, and exact description.` Y

' Myinvention relates to plants for handling 4of the coke is impaired.

coke, and particularly for conveying coke to the crushing mechanism, and has for its object to provide means for enabling uncrushed coke to be stored during the night without the loss of energy and in the quality of the coke which is experienced with the ordinary procedure.

It is customary to crush a portion of the coke produced; but on account of the careful attendance the crushing apparatus requires the crushing operation is performed in day-time'only, while at night the coke instead of being fed to the crushing apparatus is dumped in the yard. Thisv coke is then in day-timeloaded upon trucks or carts as it isthat is, uncrushed-or it is conveyed to the crushing apparatus. This procedure involves considerable additional labor, and, moreover, the coke may suffer by exposure, and the repeated handling of the coke prod uces a larger amount of fine coke or coke-dust than is produced when the coke is conveyed directly to the crushing apparatus-that is, the quality To avoid this defeet, I provide improved means for storing the uncrushed coke during the night in shelteredreceptacles, from which the coke may be discharged by gravity, so as to reduce the expense of labor.

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a coke plant provided with my improvements, parts being shown in section. Fig. 2 is a plan thereof, partly in section. Fig. 3 is a side elevation. Fig. 4 is a front elevation, partly in section,

5o of the upper portion of the elevated structure. Fig. 5 is a side elevation of the same,

partly in section.; and Figs. 6 and.7 are detail views of the hopper and spouts, partly in section.

a is the coking-furnace of any suitable construction, from which an upwardly-inclined trough or channel b leads to thecrushingapparatus d and to the storage bins or receptacles 72, arranged as will be more fully set forth hereinafter. The channel is provided with a conveyor or elevator b in the nature of a chain or apron, any approved construction being used. Ordinarily this channel l) is provided. with a door which is closed as long as it is desired to feed the coke to the crushing apparatus and which is opened when it is desired to dump the coke into the yard, as indicated in Fig. l. According to my invention, however, the coke is always lifted to the upper end of the channel b. The upper end of the channel h leads to the hopper s, connected by a tube y with three spouts or chutes c and g g. One of these spouts c leads to the crushing apparatus d of an approved construction, while the other spouts g g lead to receptacles or bins h. In the tube f is a valve or slide i for directing the coke either to the spout c or to the spouts g g. When the valve or slide t is closed, as shown in Figs. 4 and 5, and the spout c vis in the position shown in Figs. 3 and 5, the coke is directed to the crushing apparatus d. The crushed coke passes from the -crushing apparatus d through the sieve e into the elevated receptacle f, from which it may be withdrawn in the usual way. When the valve or slide t' is open, as shown in Figs. 6 and 7, and the spout c is elevated, as shown in dotted lines, Fig. 3, and full lines, Fig. 7, the coke escapes uncrushed into the receptacles or bins h, from which it may be discharged in the customary 4manner into railroad-cars or the like, sieves 7c being preferably disposed beneath each of the bins 7i. y

In practice the respective demands for crushed and uncrushed coke are such that about one-third of the total production has to be crushed. It is also found that the night production is about equal to the day-time production. Thus if the coke is allowed to run during the night into the bins h one-half of the production will be stored in the form of uncrushed coke, and to make up the required two-thirds one-third of the day production-- IOO that is, one-sixth of the total productionis added during the day, the remainder (which is one-third of the total production) being fed to the Crusher d. The capacity of the bins h should therefore be equal to two-thirds of the total production. The number of bins 71 is ofcourse immaterial, and a single bin with a single spout g might be employed.

The improved conveyer or cokehandling plant preserves the good quality of the coke and eects a considerable economy, as a double handling of the coke is avoided.

Having thus described my invention, I claim as new and desire to secure by Letters Patent* l. A coke-handling plant, comprising an elevated structure, a crushing apparatus in the upper part of the structure, a conveyer leading to the upper end of the structure, spouts at the upperend of the conveyer, and into which the conveyer discharges,one of the said spouts discharging into the crushing apparatus, and a valve for controlling the passage of the coke through said spouts, as set forth.

2. A coke-handling plant, comprising an elevated structure provided with a receptacle or bin f forI the crushed coke, and a receptacle or bin h for the uncrushed coke, a crushing apparatus in the upper part of the structure and discharging in the receptacle or bin l f, a conveyer leading to the upper end of the ERNST GEORG BERNHARD KR'IING.
